摘要： Methods and devices for receiving or transmitting a wireless packet are described. A wireless packet includes a short training field (STF) and a channel estimation field (CEF). The receiver determines whether the received STF matches an assigned STF assigned for a target link, by performing cross-correlation between the STF and a component sequence from a set of at least four different component sequences which are pairs of Golay sequences. The cross-correlation output is compared with an expected output. When the received STF matches the assigned STF, the wireless packet is considered a target packet. A channel estimation is performed using a cross-correlation of the received CEF with an assigned CEF assigned for the target link. The assigned CEF is from a set of two or more CEFs, where each CEF is formed using the set of component sequences, and the CEFs are pairwise zero-correlation zone (ZCZ) sequences.

摘要： The present disclosure provides for a method and apparatus for efficient cross-correlation between a reference sequence and a received sequence in a wireless communication system. The reference sequence includes a concatenation of sign-adjusted sub-sequences, the sign adjustments determined by a first sign sequence of a set of sign sequences. For example, the reference sequence may be an alternating concatenation of sign-adjusted Golay complementary pair sub-sequences. The received sequence is shifted to provide a plurality of time shifted sequences that are then cross-correlated with the sub-sequences to form a set of partial cross-correlations. The partial cross-correlations are sign-adjusted using the first sign sequence and combined to produce the cross-correlation between the reference sequence and the received sequence. The cross-correlations so produced may be used for channel signature (e.g. PHY-type) identification and/or channel impulse response estimation.
